Every meridian of longitude is perpendicular to every parallel of latitude, and every parallel of latitude is perpendicular to every meridian of longitude.
look at a pencil. it is only hexagonal prism i can think of. bye.
The zero vector is not perpendicular to all vectors, but it is orthogonal to all vectors.
The axis of a right circular cone is perpendicular to every radius or diameter of the base.
no but sometimes yes

Yes. There can be a line perpendicular to the given line at every point on it, and you know how many different points there are on it ...

the opposite of parallel lines are Perpendicular. A perpendicular angle or line is where there is a 90 degree on each and every side.
Perpendicular lines intersect to form right (90 degree) angles every time.
I believe the answer is "perpendicular line". Forgive me if I'm wrong :)
